It seems to me that at the implementation stage, the things that never change and the things that do change are the same. For example, customers will always want low prices and fast delivery. Internet ordering and robots in warehouses are things that change. But the changes are better ways to fulfill the unchanging needs. So Bezos sees investments in internet ordering and robots as investments in what does not change. Whereas Andreessen sees the same investments as betting on change. So what difference does their point of view make if both entrepreneurs end up making the same investments?
